What a rent increase letter needs

A rent increase letter is the formal, written notice that a landlord gives before raising rent. To be clear and enforceable it should leave no ambiguity about who, how much, and when. Include:

Who it's for — the tenant's name and the full property address, including unit number.
The numbers — the current rent, the new rent, and (helpful) the difference.
The dates — the date of the notice and the date the new rent takes effect.
A reason (optional but smart) — a brief line such as rising taxes or maintenance costs keeps the tone professional.
Your contact info — so the tenant can respond or ask questions.

The generator above drops all of this into a standard business-letter layout.

How much notice to give

Most states require 30 to 60 days' written notice before a rent increase takes effect, and the required period often depends on the size of the increase. Rules vary by state and city, so confirm your local requirement before you set the effective date. See our per-state rent-increase notice guide and rent control laws by state.

Send it so it counts

Deliver the notice in a way your lease and state law allow — certified mail, first-class mail, personal delivery, or email where permitted — and keep a copy for your records. The generator has a delivery-method field so the letter states how it was sent.

Set the new number with real data

Before you pick the new rent, make sure it matches the market — too high invites vacancy, too low leaves money on the table. Pull a free rent estimate for the address to anchor it, and if a tenant pushes back, our guide to justifying a rent number helps you make the case.
